# In radiography, a longer gray scale of contrast can be accomplished through:
A. Increasing the focal spot-skin distance
B. Increasing the kilovoltage
C. Decreasing the filtration
D. Increasing the milliamperage

The correct answer is B. Increasing the kilovoltage.

Longer gray scales of contrast can be
achieved by increasing the kilovoltage peak.

Increasing the kilovoltage causes the
radiographic image to have low contrast
and longer gray scales.

Low kilovoltage creates low energy x-rays
responsible for producing high contrast and
shorter gray scale.
